20. A method implemented by a vehicle thermal management system comprising control electronics, the vehicle thermal management system being configured for inclusion in a vehicle, wherein the method comprises:
obtaining input information from a controller associated with a cabin cooling system, a measure associated with fogging in a cabin of the vehicle, and range information associated with the vehicle; and
selecting between a plurality of modes based on the input information, wherein the vehicle thermal management system further comprises:
a vehicle heat pump comprising the cabin cooling system and a radiator, and
a coolant valve system configured to operate in the plurality of modes, wherein each mode is associated with one or more coolant loops, wherein each coolant loop connects a different subset of the cabin cooling system, the radiator, a battery coolant loop, and a drive train coolant loop,
and wherein selection of a mode causes adjustments of serial and/or parallel connections between individual coolant loops associated with the selected mode.
